What is the nickname for the most powerful nuclear weapon ever detonated?

It is a worry that Putin has the largest nuclear arsenal. I wish they were never invented.

Kiwozzie, I live in the state and city of Los Alamos where they had the Manhattan Project. This is where Oppenheimer created the atomic bomb. His quote, "My God, what have I done." He was right. But it did end the war.

Rey, at least we hope and pray they never do/will.

50mt is nothing compared to the latest thermonuclear weapons.
